On a number line, if we choose a number a, all the numbers to the right of a are greater than a, while all the numbers to the left are lower than a.
In this case, the inequality is:
[tex]x<-1[/tex]
So, the solution in the number line would be all the numbers to the left of -1.
Therefore, this number line does not represent the solution to x<-1 because everything is to the right instead of to the left.
